USB Drives Mold

I need a custom USB drive. I will need about 1000 pieces every four months. Companies have quoted me $80-$100 for the mould. That's what I intend to pay for the mould (unless there is a reason to pay more). You can request for the drawing files to my mail. State at the heading "USB MANUFACTURER REQUESTING FILES" I have asked 3 companies to make this mould, but for some reason or other, they have not completed the design. I REALLY NEED IT. Please let's sucess this time! Thanks in advance.
